ATTORNEYS Patented Apr. 30, 1940 UNITED STATES PATENT OFFICE 3 Claims.

This invention aims to provide a simple means for cutting down to the desired diameter, a washer which is used in connection with spigots or for any other purpose.

Fig. 1 shows, in side elevation, a device constructed in accordance with the invention, Fig. 2 is a longitudinal section wherein parts remain in elevation, Fig. 3 is an end elevation, and Fig. 4 is a cross section on the line 4-4 of Fig. 2.

The device comprises an elongated body I, preferably made of metal, as are the other parts of the article, the body I including a cylindrical shank or handle 2 and a conical head 3. The handle 2 has a cylindrical bearing bore 4, and the conical head 3 has a conical mouth 5. In the head 3 of the body I there is an elongated opening or slot 6. One wall I of the slot 6 has a slant that is approximately tangential to the mouth 5, as shown in Fig. 4. The said wall I also has an inward slant, toward the longitudinal axis of the body I, as Fig. 2 will disclose. The wall of the slot 6 that is opposite to the wall I is marked by the numeral 8 and is disposed in substantially radial relation with respect to the longitudinal axis of the body I, as Fig. 4 will make manifest. Along the head 3, adiacent to the outer edge of the wall 8, extends a scale 9.

A blade Ill is attached by securing elements II, such as screws, to the wall I of the slot 8. The blade I0 is provided with transverse slots I2 in its outer edge, these slots receiving the screws II, and the construction being such that the blade I0 can be adjusted in or out. Because the blade l0 can be adjusted in or out, a greater or less amount of its cutting edge may be disposed within the mouth 5 of the head 3. The tangential disposition of the wall I and of the blade I0 with respect to the mouth 5 of the head 3 makes the blade out easily. The slant of the blade I0, lengthwise of the head 3, makes it possible for the washer to be trimmed down to any desired diameter, an observation which probably will be obvious at this point in the decription, although further explanation is given hereinafter.

A shaft I4 is Journaled in the bearing bore 4, and is mounted for longitudinal movement therein. One end of the shaft I4 extends into the mouth 5. The opposite end of the shaft I4 carries a turning button Iii or any other element whereby an operator can rotate the shaft and move it endwise. The washer I8 which is to be sized is mounted removably on one end of the shaft I4, by means of a securing device, such as a screw I1.

By means of the turning button I5, the operator slides the shaft I4 endwise, to the position of Fig. l, in which the shaft extends a little way beyond the outer end of the head 3. The washer I6 then is secured to the end of the shaft I4 by the screw IT. The operator pulls the washer I6 into the mouth 5 by means of the button I6 and the shaft I4, and at the same time, he rotates the shaft. The washer I6 is rotated, along with the shaft I4, and as the washer advances into the mouth 5, the washer is cut down to the required diameter by contact with the edge of the blade Ill. The operator of course can reduce the diameter of the washer I6 by a cut and try method, but it is better to note where the washer I6 comes on the scale 9, as the trimming of the washer proceeds. In this way, the diameter to which the washer I6 has been trimmed, can be ascertained by inspection. No numbers or other characters are shown in connection with the scale 9. The manufacturer can number the scale as he wishes, either to indicate the diameter of the washer or to indicate the trade number applied to a washer of any particular diameter.

The device shown in the drawing, described in the specification, and hereinafter claimed is characterized by simplicity, strength, low cost, effectiveness and ability to stand much grief without expert attention.

What is claimed is:

1. A washer sizer comprising a body provided with an inwardly-tapered mouth, a blade mounted on the body and having a cutting edge approximating the taper of the mouth, the cutting edge extending into the mouth, a shaft Journaled in the body and mounted to move longitudinally therein, and means for securing a washer detachably to the shaft, in operative relation to the cutting edge of the blade and in circumferentially supported relation with respect to the mouth, the shaft being definitely associated with the body. as a part of the sizer, when the washer is removed.

2. The washer sizer of claim 1, in combination with means for securing the blade to the body for adjustment toward and away from the axis of rotation of the shaft. v

3. A washer sizer comprising a body provided at one end with a shank and having an inwardlytapered mouth at its opposite end, the mouthed portion of the body having a longitudinal slot, a blade mounted on one wall of the slot and having a cutting edge extended into the mouth, the cutting edge of the blade approximating the taper of the mouth, the shank having a bore communicating with the mouth, a shaft Journaled in the bore and mounted for longitudinal movement therein, means for securing a washer to one end of the shaft detachably, in operative relation to the cutting edge of the blade and in circumferentially supported relation with respect to the mouth, and a device on the opposite end of the shaft whereby an operator may rotate the shaft and move the shaft longitudinally, the shaft being long enough so that whilst said device is exposed at said one end of the body, said means will be exposed at said opposite end of the body, the shank being long enough to afford a practically efllcient handle, and to lengthen the bore to such an extent that it will form a long-wearing bearing for the shaft and support the shaft adequately for longitudinal reciprocation.
